0.2 VCC + 0.9

0.2 VCC - 0.1

AC inputs during testing are driven at VCC - 0.5 for a logic “1” and 0.45V for a logic “0”.

Timing measurement are made at VIH min for a logic “1” and VIL max for a logic “0”.

FLOAT

VOH - 0.1 V

VOL + 0.1 V

VLOAD

VLOAD + 0.1 V

VLOAD - 0.1 V

For timing purposes as port pin is no longer floating when a 100 mV change from load

voltage occurs and begins to float when a 100 mV change from the loaded VOH/VOL level

occurs. IOL/IOH ≥ ± 20 mA.
